awue/wlioz FASTENING FOR TOOIEHEADS.

To all whom it may concern:

Beit known that I, Jnssn S. CLIMENSON, a citizen of the United States, residing at Honey Brook, in the county of Chester and State of Pennsylvania, have invented a new and useful Fastening for Tool-Heads, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for fastening a tool head to a handle, the structure being of peculiar utility in con nection with a brick layers scutch, although the invention is capable of other uses.

The invention aims to "provide novel means whereby one head may be substituted for another, on a tool handle, and to provide novel means whereby the head may besecured to the handle.

Specifically, the invention aims to improve the construction of a wedge, which, being inserted between a pair of jaws on a handle, expands the jaws, and causes the jaws to cooperate with the head of a tool.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

' In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the present invention; Fig. 2 is an elevation wherein the structure is viewed at right angles to the showing of Fig. 1; Fig. 3 is a detail enlarged from Fig. 1, parts being broken away; Fig. 4: is a section taken approximately on the line L4 of Fig. 3; Fig. 5 is a section taken approximately on the line 55 of Fig. 3; Fig. 6 is a perspective view showing the wedge; Fig. 7 is an end elevation of the handle; and Fig. 8 is a side elevation showing a slight modification in the invention.

In carrying out the invention there is provided a head 1 having chisel ends 2 and provided with an undercut seat 3 which extends entirely across the head. The head may be of any desired form, and thus in Specification of Letters Patent.

Patented Feb. 11, 1919.

Application filed May 4, 1918. Serial No. 232,566.

Fig. 8, there is shown a head 4: having a The numeral 8 marks a handle, which may be variously constructed, the handle in the present instance, including a web 9 terminating in a boss 10, and side pieces 11 cooperating with the web 9 and the boss 10 and held in place by securing devices 12.

There is an opening 14: through the boss 10, the opening communicating with a re duced slot 15, which, in its turn, communicat-es with the apex of a V-shaped recess 16 in the boss, there being a reduced passage 17 in the end of the boss 10, the passage 17 communicating with the recess 16 and defining flanges 21 which overhang the recess. The inner edges of the flanges 21 converge, as shown at 22. The opening 14, the slot 15, the recess 16 and the passage 17 divide the boss 10 and form jaws 18, having some little resiliency, and adapted to be inserted into the seat 3 of the head 1, transversely of the head, in a manner which will be entirely clear when Figs. 1 and 3 are examined. As shown at 19, the walls of the V-shaped recess 16 converge longitudinally of the handle 8, and as denoted by the numeral 20, the walls of the recess 16 converge transversely of the handle 8.

The numeral 23 denotes a wedge, the side faces of which converge longitudinally of the handle 8, as shown at 24. The wedge 23 tapers from end to end, transversely of the handle 8, as denoted by the numeral 25. The butt of thewedge is shown at 26 and carries a rib 27. The side surfaces of the rib 27 converge transversely of the handle, as denoted by the numeral 28.

In practical operation, after the jaws 18 have been inserted into the undercut recess 3 of the head 1, the wedge 23 is inserted endwise into the V-shaped recess 16. Since the wedge 23 tapers longitudinally, and since the wedge tapers transversely, the wedge will be crowded transversely, and in the direction of the length of the handle, when the wedge moves into the recess, transversely of the handle. This operation, obviously, spreads the jaws 18 and causes them to cooperate with the seat 3 in the head 1. Since the side surfaces of the rib 27 on the wedge converge as shown at 28, these surfaces, coacting with the converging edges 22 of-the flanges 21, aid, further, in spreading the jaws 18 apart.

Having thus described the invention, what is claimed is 1. In a device of the class described, a head having a transverse undercut seat; a handle including jaws insertible transversely of the head into the seat; and a wedge insertible between the jaws transversely'of the handle and independently of the head.

2. In, a device of the class described, a head having. a transverse undercut seat; a handle cleft longitudinally to form: jaws insertible transversely of the head into: the seat and provided between the jaws with a recesswhich convergeslongitudinally of the handle and. tapers transversely of the. handle; and a wedge insertible into the recess transversely of the handle, the wedge converging longitudinally of the handle and tapering transversely of the handle to conform to the recess.

3. In a device of the class described, a head having a. transverse undercut seat; a

jaws which are insertible into the seat transversely of the head; and a wedge insertible into the recess transversel of the, handle, the wedge converging long tudinally of the handle and tapering transversely of the handle, the wedge including; a rib received between the flanges and tapering; trans versely of the handle to cooperate. with the inner edges. of. the flanges.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in! the presence of'two'witnesses.
